Re: [Xen-users] Best Distro for Xen, Software Raid and LVM

["Tony Hernandez" <ttony.hernandez@xxxxxxxxx>]

I would like to put the root directory on raid.

Here is my problem.  I will be using Xen in a production role.  I need the redundancy of raid-1.  I don't have a "real" raid controller (the motherboard has "fake" raid).  I have two sata drives in this box and wan to maximize the space for DomUs.  So having I figure having two drives, raided with raid-1 (via software), then LVM on top of that.  Then have Dom0 in a logical volume and all the DomUs in subsequent volumes.

Does anyone know what options to pass initrd to use software raid (not sure what MegaRaid is) and LVM?

Regards,
Tony

Are you trying to put your root directory (/) onto software raid?  If
so, that, not your distribution, may be the problem -- as far as LILO is
concerned.  Also, note that your root device should be running ext2 or
ext3 if you want the path of least resistance with the linux kernel
binaries shipped by Xensource.

I'm running Xen on Debian and Ubuntu as hosts...
